Given numbers are 813, 790, 673, 258

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(813, 790) = 642270

GCD(813, 790) = ( 813 x 790 ) / 642270

= 813 / 790

= 813

Step2:

LCM(1, 673) = 673

GCD(1, 673) = ( 1 x 673 ) / 673

= 1 / 673

= 1

Step3:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

So, Greatest Common Divisor of 813, 790, 673, 258 is 1
